Avariety of different mechanisms in nature create diversity in organism populations. the tundra found in the northernmost parts of the planet is the world’s youngest biome. the tundra is home to a variety of plants and animals. organisms that can be found in the tundra include shrubs, mosses, caribou, polar bears, and wolves. which mechanism do the different organism populations found across the tundra exemplify?

1. genetic diversity
2. ecosystem diversity
3. species diversity
4. variation

In the Tundra region, the diversity of the organisms present is high. Multiple different species of different organisms are present in these regions, which makes them a diverse area on the Earth. The mechanism responsible for these different populations is the species diversity.

It can be defined as the total number of species that are present in a given community.

Hence, the correct answer is option 3.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
